When your check engine light pops on, it can feel like a mystery wrapped in an enigma. Thankfully, AutoZone offers car diagnostic tests to help decode those cryptic dashboard warnings. But before you head to your nearest store, it’s crucial to understand what these tests entail, their limitations, and what to expect.
Demystifying the AutoZone Car Diagnostic Test
AutoZone’s free car diagnostic test uses a scan tool, also known as an OBD2 scanner, to read your car’s computer and retrieve diagnostic trouble codes (DTCs). Think of it like plugging into your car’s brain to understand why it’s feeling under the weather.

Limitations of AutoZone’s Diagnostic Test
While AutoZone’s test can be incredibly helpful, it’s crucial to understand its limitations:
